India successfully tested its surface-to-ground ballistic missile capable of nuclear Agni-5, the most advanced Agni missile with a range of more than 5000 km, from a test range on the Odisha coast on Thursday. .
The associated test flight of the missile user has further boosted the capabilities of indigenous missiles and the country's deterrent force.
All radars, tracking systems and range stations monitored flight performance, defense sources said.
Describing the trial as "totally successful," the sources said, the sophisticated missile traveled for 19 minutes and covered 4,900 km.
The elegant missile was tested from a boat launcher, mounted on a mobile platform, at approximately 9.54 am from No.4. The Integrated Test Range (ITR) launch pad on Abdul Kalam Island, formerly known as Wheeler Island, they said.
After four successful development trials, this was the first associated user test of Agni-5 missi le, the sources added.
Agni-5 is the most advanced missile of the Agni series with new technologies incorporated into it in terms of navigation and guidance, warheads and engines. It has a range of more than 5000 km.
"The redundant navigation systems, the Very High Precision Inertial Navigation System (RINS) Ring Laser Gyro and the most modern and accurate Micro Navigation System (MINS) ensured that the missile reached the target point a few meters from precision.
"High-speed onboard computer and fault-tolerant software together with a robust and reliable bus guided the missile smoothly," said an official with the Defense Research and Development Organization (DRDO).
The missile is so programmed that after reaching the highest point of its trajectory it will go towards the Earth to continue its journey towards the desired objective with an increased speed due to the attraction of the earth's gravitational pull, he said.
Its path is precisely directed by the advanced on-board computer and the inertial navigation system, the official added.
The first two flights exi of Agni-5 in 2012 and 2013 were made in open configuration.  The third, fourth, and Thursday launch of a boat, integrated with a sophisticated mobile launcher, were in its deliverable configuration that allows the launch of the missile with a very short setup time compared to an open setup.
It also has advantages of greater reliability, longer life, less maintenance and improved mobility.
India currently has in its arsenal of the Agni series, Agni-1 with 700 km range, Agni-2 with a range of 2000 km, Agni-3 and Agni. 4 with 2500 km to more than 3500 km.
The first Agni-5 test was held on April 19, 2012, the second on September 15, 2013, the third on January 31, 2015 and the fourth test on December 26. 2016 from the same base.
